From the website:
off•JERK•me is a role-playing poem for 2-6 players that takes about 5 minutes to play.
This game is about exploring blocking.
One of the players will play the Jerk. The other players will play British People Who Don't Want To Make A Fuss.
The Jerk and the British People are playing a parlour narration game […]. The Jerk however, thinks this is dumb.
